In the search for new energy resources, scientists have discovered ways to use the Earth itself as a valuable source of power. Geothermal power plants use the Earth's natural underground heat to provide clean, renewable energy. The geothermal energy industry has expanded rapidly in recent years as interest in renewable energy has grown. In 2011, the U.S. Bureau of Labor Statistics (BLS) counted about 1,050 jobs in geothermal power generation. And the Geothermal Energy Association estimates that there were about 5,200 jobs directly related to geothermal power production and management in the United States in 2010. Geothermal energy production is expected to continue to grow, and with it the demand for workers in associated occupations. This article describes geothermal energy and career opportunities in the industry, focusing on geothermal projects that generate electricity for power grids. The first two sections explain geothermal energy and how it works, and the third section discusses the different steps necessary to construct a geothermal plant. The fourth section highlights occupations that are critical to the geothermal industry. Each occupational overview includes information on job duties; occupational wage and employment data; and the credentials needed to work in these occupations, such as education, training, certification, and licensure. Sources for more information are listed at the end of the article. (Contains 4 tables.)
